Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First, some technical terms related to the present application are explained:
a Linux Container (LXC) is a kernel virtualization technology that can provide lightweight virtualization to isolate processes and resources. The technology is characterized by kernel-mode sharing and user-mode isolation, namely, a plurality of virtual machine systems share the kernel of a host machine system.
The virtual machine monitor (Hypervisor) is software, firmware or hardware used for establishing and executing a virtual machine, and the technical characteristic is that the virtual machine system independently uses the kernel of a host system, but the two share hardware resources.
Currently, a vehicle machine has multiple start schemes, for example, a LXC-based multiple system start scheme and a virtual machine monitor-based multiple system start scheme.
In a multi-system starting scheme based on the LXC, under a low power consumption mode, a kernel of a host system enters deep sleep, and most user services are suspended, so that the power consumption can be greatly reduced. However, the instrument system and the entertainment system of the vehicle machine share a kernel, the former enters a low power consumption mode, the latter is suspended in service, and a user cannot use the entertainment system in the low power consumption mode.
In a hypervisor-based multi-system boot scheme, the kernel of the instrumentation system and the kernel of the entertainment system are independent, but share hardware resources. Therefore, if a user experiences entertainment system services, such as listening to a broadcast, during non-driving time, the meter system still occupies hardware resources such as a Central Processing Unit (CPU) or a network, which causes a problem of power consumption of the meter system in a non-use state, and a problem of jamming caused by the fact that the entertainment system cannot fully use the hardware resources of the vehicle and the CPU, which affects user experience. At present, the scene is very common in the vehicle machine system integration trend.
Based on the above problems, the present application provides an energy saving method, an energy saving device and a storage medium for an instrument system, which make full use of the virtualization technical characteristics of a virtual machine monitor, and can process the instrument system and an entertainment system in a differentiated manner during the non-driving time of a user, thereby saving the electric quantity of the instrument system, prolonging the battery life, and increasing the experience of the entertainment system used by the user.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, in the present application scenario, a vehicle machine inside the vehicle 10 employs a multiple system starting scheme based on a virtual machine monitor, and in the vehicle machine, the multiple systems include but are not limited to a host system, a meter system and an entertainment system, wherein the host system starts the virtual machine monitor, configures a virtualization environment, and runs the meter system and the entertainment system in the virtual machine monitor. The instrument system is used for transmitting the state of the vehicle to a user through the dial plate, and the entertainment system is used for meeting the entertainment requirements of the user.
For example, when a user has a need to use an entertainment system in a car, the car can communicate with the server 20, obtain entertainment content stored in the server 20, and output the entertainment content to the user through an audio/video playing device carried by the car, so as to meet the need of the user for entertainment through the car.
When the user still needs to use the entertainment system when the vehicle 10 is in the flameout state, the in-vehicle machine controls the normal operation of the entertainment system while controlling the instrument system to enter the sleep state.
It should be noted that fig. 1 is only a schematic diagram of an application scenario provided in this embodiment, and this embodiment of the present application does not limit the devices included in fig. 1, and also does not limit the positional relationship between the devices in fig. 1. For example, in the application scenario shown in fig. 1, a data storage device may be further included, and the data storage device may be an external memory with respect to the car machine or the server 20, or may be a memory integrated inside the car machine or the server 20.
In addition, to ensure safe driving of the user, the user may use the entertainment system during non-driving times.
Next, a meter system energy saving method will be described by way of specific embodiments.
Fig. 2 is a flowchart of an energy saving method for a meter system according to an embodiment of the present application. The embodiment of the application provides an energy-saving method for an instrument system, which is applied to a vehicle machine based on a multi-system starting scheme of a virtual machine monitor, such as a vehicle 10 shown in fig. 1. In the method, when a user is not driving, the instrument system is in a low power consumption mode, the kernel of the instrument system enters a sleep mode, but the kernel of the entertainment system normally operates, and the entertainment system can fully use hardware resources such as a CPU (Central processing Unit) and a network, so that the operating smoothness of the entertainment system is improved.
Specifically, as shown in fig. 2, the meter system energy saving method includes:
s201, after a power supply starting command is detected, a virtualization environment is configured.
Because the car machine is based on a multi-system starting scheme of a virtual machine monitor, an instrument system and an entertainment system of the car machine run in a virtualization environment, and the virtualization environment needs to be configured before the instrument system and the entertainment system run. Therefore, the vehicle first configures the virtualized environment after detecting the power start instruction.
S202, operating the instrument system and the entertainment system in the virtualization environment, and starting timing by the instrument system.
After running the instrumentation system and the entertainment system in the virtualized environment, the instrumentation system starts timing, and specifically, the timing method may be to start a timer for ignition or not. For example, the preset duration of the timer may be 2 minutes, and the timing manner may be a countdown or a forward timing, which is not limited in this application. The purpose of the timer is to operate the vehicle automatically when it is not manually intervened. Specifically, for example, when the power of the vehicle is turned on, the driver may not be at the side of the vehicle, or the driver is talking, and therefore cannot control the vehicle at this time, and in order to save the amount of electricity, the operating state of the meter system is adjusted by setting a timer.
S203, if the ignition instruction is not detected within the preset timed duration, controlling the instrument system to enter a sleep mode, and controlling the entertainment system to normally operate.
If the ignition operation is not performed by the driver within 2 minutes within the preset time, and accordingly the vehicle does not detect the ignition instruction, the vehicle control instrument system enters the sleep mode, and the entertainment system still normally operates without being affected.
Specifically, after the instrument system enters the sleep mode, the kernel of the instrument system is in the low power consumption mode, the power consumption of the kernel is very little, and hardware resources, a CPU and the like of the vehicle machine are not used any more, so that the entertainment system can fully use the hardware resources and the CPU of the vehicle machine to avoid the blocking phenomenon.
In the embodiment of the application, after a power supply starting instruction is detected by a vehicle, a virtualized environment is configured first, and an instrument system and an entertainment system are operated in the virtualized environment, wherein the instrument system starts timing, and if an ignition instruction is not detected within a preset time length of timing, the instrument system is controlled to enter a sleep mode, and the entertainment system is controlled to operate normally. If the ignition instruction is not detected within the preset timed duration, which indicates that the user has no ignition requirement, the instrument system is controlled to enter the sleep mode under the condition, on one hand, the power consumption of the instrument system in the sleep mode can be ignored, so that the power consumption can be reduced, and the service life of the battery can be prolonged; on the other hand, since the meter system in the sleep mode does not use hardware resources and a CPU, a stuck problem of the entertainment system can be avoided.
On the basis of the above embodiment, the instrumentation system in the sleep mode may include at least one of the following states: applications in the instrumentation system are stopped or suspended; the instrument backlight in the instrument system is extinguished, etc. It can be understood that the sleep mode may be defined as that the kernel of the host system continues to run, most applications in the meter system are stopped, other applications enter the suspend mode, the suspended processes run periodically, and the tasks of the processes are delayed, which mainly aims to reduce the CPU consumption and network pressure of the meter system and reduce the occupation of hardware resources by the meter system. Meanwhile, the instrument backlight in the instrument system is turned off, and the electric quantity loss is further reduced.
In the embodiment of the application, after the instrument system enters the sleep mode, the instrument backlight of the instrument system is turned off, so that the power consumption of the instrument system is reduced; meanwhile, the application in the instrument system is stopped or suspended, and hardware resources and a CPU are not occupied, so that the entertainment system sharing the hardware resources with the instrument system can fully use the hardware resources and the CPU of the vehicle machine.
On the basis of the foregoing embodiment, optionally, configuring the virtualized environment after detecting that the power supply is started may include: after detecting that the power supply is started, starting a host machine system; and starting a virtual machine monitor in the host system and configuring a virtualization environment.
After the vehicle starts the power supply, the vehicle machine needs to start the host system in order to start the virtual machine monitor and configure the virtualization environment. Illustratively, the host system may be an operating system of the host. The virtual machine monitor can be software, and plays a role in building a platform for sharing the virtual machine system and the hardware resources of the host machine, so that the virtual machine system can also use the hardware resources of the host machine end. The virtual machine monitor configures the virtual environment in a manner of setting an address of an IP and setting a gateway in the virtual machine monitor. Finally, running the instrumentation system and the entertainment system in a virtualized environment can be viewed as running two new virtual machine systems in the virtual machine monitor, which still occupy the hardware resources and kernel of the host machine.
Optionally, the vehicle control entertainment system remains in a normal operating mode until the user turns off the entertainment system. In addition, considering that the battery capacity may be too low during the use of the entertainment system, the normal use of the vehicle may be affected. Therefore, in some embodiments, the meter system energy saving method may further include: detecting whether the electric quantity of the battery is smaller than an electric quantity threshold value or not in the normal operation process of the entertainment system; if the battery electric quantity is smaller than the electric quantity threshold value, the instrument system is awakened to enter a normal operation mode from the sleep mode, and the instrument system in the normal operation mode prompts that the battery electric quantity is smaller than the electric quantity threshold value.
Specifically, when the battery power is reduced to the power threshold, the host automatically wakes up the kernel of the instrument system, and starts the power alarm program to prompt the user that the power is insufficient.
In this implementation, a power threshold is preset in the vehicle, and the power threshold is used to represent the minimum power when the vehicle can be used normally. The magnitude of the power threshold may be set based on historical experience. Illustratively, the threshold may be 20%.
It should be noted that the electric quantity threshold value may be applicable to the case where only the entertainment system is normally operated, or may be applicable to the case where both the entertainment system and the meter system are normally operated. For example, in the case that only the entertainment system is operating normally, the meter system is in the sleep mode, when the battery power is detected to be less than 20%, the meter system of the vehicle machine is automatically awakened, and the meter system starts the power alarm program to indicate that the power of the driver is insufficient on the dial. Similarly, under the condition that the entertainment system and the instrument system both run normally, when the electric quantity of the vehicle is detected to be less than 20%, the instrument system can start an electric quantity warning program to indicate that the electric quantity of the driver is insufficient on the dial plate. The driver can select charging or power off according to actual conditions. In addition, when the vehicle electric quantity is larger than the threshold value by 20% after recharging, the electric quantity warning program is stopped to be executed, and the indication that the electric quantity on the dial is insufficient disappears.
In addition, the energy saving method for the meter system provided by the embodiment of the application can further comprise the following steps: and if the ignition instruction is detected within the preset time length of timing, controlling the normal operation of the instrument system.
This embodiment describes the case corresponding to S203, that is, the ignition is performed shortly after the driver gets on the vehicle, and at this time, the meter system and the entertainment system both operate normally, and the meter system does not enter the sleep mode.
Still further, the energy saving method for the meter system provided by the embodiment of the application may further include: and if a flameout instruction is detected, controlling the instrument system to enter a sleep mode and controlling the entertainment system to normally operate.
This embodiment is applied to a scenario where the vehicle has been ignited. When the driver stops the vehicle, the instrument system of the vehicle machine automatically enters a sleep mode, the entertainment system still operates normally, and the driver still can access the application in the entertainment system. When the driver turns off the vehicle power, the vehicle is powered off, and all systems are turned off.
In connection with the above embodiments, for example, when a driver gets on a vehicle and turns on a power supply of a vehicle such as an automobile, a host system of the vehicle starts to operate, and a virtual machine monitor is turned on in the host system, and a virtualization environment is configured by the virtual machine monitor. The method comprises the steps that an instrument system and an entertainment system are started in a virtual environment, meanwhile, the instrument system starts a timer for judging whether ignition is carried out or not, if ignition is carried out within preset time, the instrument system and the entertainment system of a vehicle machine run normally, a driver can access applications in the two systems at the same time, for example, the driver can listen to broadcasting or be connected with a mobile phone through Bluetooth to play music, and the current running speed of a vehicle and the temperature outside the vehicle can be obtained through a dial plate in the instrument system. Or if the driver does not ignite within the preset time, the instrument system enters a sleep mode, the dial is backlit, the application in the instrument system is stopped or suspended, the entertainment system is not affected by the fact that the instrument system is closed before, and the driver still can access the application of the entertainment system. When a driver needs to stop and put out the vehicle in the driving process, after the flameout instruction is pressed, the instrument system can automatically enter the sleep mode, the instrument dial is in backlight, and the driver can still access the application of the entertainment system.
It should be emphasized that the premise that the in-vehicle control entertainment system in the above embodiment is always in the normal operation mode is that the user has a need to use the entertainment system, and if the user turns off the entertainment system, the vehicle control entertainment system enters the sleep mode or the off mode.
Fig. 3 is a flowchart of an energy saving method for a meter system according to another embodiment of the present application. Referring to fig. 3, a specific implementation of the energy saving method for an instrumentation system provided by the present application is shown.
S301, starting a vehicle power supply, and electrifying all electronic equipment in the vehicle.
S302, the host machine system is started normally, and the virtual machine monitor virtualization environment is configured by the starting program.
A Host system (Host operating system, abbreviated as Host OS) is defined as an operating system running on physical hardware in a virtual machine monitor virtualization environment. The Guest OS referred to below is defined as a virtual machine operating system running on a virtual machine monitor.
And S303, running an instrument system and an entertainment system by the virtual machine monitor, wherein the instrument system starts a two-minute timer for judging whether the vehicle is ignited or not.
And after the configuration of the virtual environment is finished, normally operating the instrument system and the entertainment system in the virtual environment. The meter system may also be referred to as a meter Guest OS, and the entertainment system may also be referred to as an entertainment Guest OS, among others. Illustratively, the meter system starts a countdown timer that fires or not within two minutes.
S304, ignition or not within two minutes?
If the driver has a driving demand within two minutes and the ignition is performed before the countdown is finished, executing step S305; if the driver has no driving demand for two minutes and has not fired before the countdown, step S308 is executed.
And S305, controlling the normal operation of the instrument system.
After ignition, the instrument system normally runs, the backlight of the instrument panel is turned on, and the application in the instrument system can normally use hardware resources in the host machine. The driver can obtain the speed, the oil mass, the temperature outside the automobile and various information of the automobile through the dial.
And S306, after the vehicle is stopped and flamed out, the instrument system enters a sleep mode.
In the sleep mode, the backlight of the instrumentation system is turned off and access to hardware resources is limited.
When the driver is ignited and flamed out, the instrument system does not need to wait for the timer of 2 minutes to finish timing, and directly and automatically enters the sleep mode.
S307, detecting whether the user turns off the power supply?
If the user turns off the power supply, the whole process is finished; if the user does not turn off the power, S309 is performed.
And S308, controlling the instrument system to enter a sleep mode.
The driver does not carry out ignition operation within two minutes, the instrument system automatically enters a sleep mode, the instrument system is in a low power consumption mode at the moment, the kernel of the instrument system enters a sleep state, and the power consumption of the instrument system running in the sleep mode can be ignored, so that the power consumption problem of the instrument system is solved.
And S309, controlling the entertainment system to operate independently.
At the moment, the entertainment system fully uses the CPU and hardware resources of the car machine, and a user can better experience the in-car entertainment service.
Because the meter system and the entertainment system kernel are independent, the kernel of the entertainment system operates normally. And because the application of the instrument system is stopped or suspended, hardware resources are not occupied, so that the entertainment system can fully use hardware resources such as a CPU (central processing unit), a network and the like, and the problem of blocking caused by the fact that the in-vehicle entertainment system cannot fully use the hardware resources can be solved to a certain extent, thereby increasing the running smoothness of the entertainment system.
S310, whether the battery level is lower than a threshold?
If the battery power is lower than the threshold, step S311 is executed, and if the battery power is not lower than the threshold, the monitoring is continued, and step S309 is continued.
S311, waking up the kernel of the instrument system, operating the electric quantity warning program and prompting the user that the current battery electric quantity is too low.
